I took my motor apart yesterday, and damn is it in bad shape... I mean, the piston head is sort of blackened, the when i have my cooling head off the engine, there is no resistance when the piston arrives at the top of the cylinder. it has some compression though, when the piston enters the bottom of the cylinder i can hear air being pushed through the valves.. regardless i am bummed about this. i had a bad crash a few weeks back and took my engine apart and didnt see anything wrong, but maybe i shouldve checked the piston sleeve for pinch.. such a BUMMER! i take partial blame to this seeing how the crash messed with my engine being sealed a little so it was running lean.
